Code P0262 2012 Ford Fusion Description

The P0262 diagnostic trouble code (DTC) for a 2012 Ford Fusion indicates an issue with the Cylinder 1 Injector Circuit being too high. This means that the fuel injector for cylinder 1 is sending a higher than expected voltage signal to the engine control module (ECM). The ECM uses this signal to control the amount of fuel being injected into the cylinder for combustion. When the voltage is too high, it can lead to an imbalance in the air-fuel mixture, potentially causing rough idling, poor fuel economy, and even engine misfires.
